The couple are currently looking after the future King while his parents, the Duke and Duchess of Cambridge, holiday without him.

William and Kate are vacationing at a luxurious Indian Ocean resort, while Kate’s parents look after their seven-month-old.

According to a family insider, the Middletons are taking the opportunity to spoil their first grandson.

"[They are] spoiling him rotten, just like any other grandparents," the source told People Magazine. "They are just overwhelmed to be grandparents. They are helping out in whatever way they can and wherever they are able to – you always do with your own family, don't you?"

Carole and Michael will take looking after their grandson in their stride, as they were on hand to support Kate as soon as she left hospital last July.

The 32-year-old spent the first few weeks after the birth at her parents’ Berkshire county home.

While Prince George now has a nanny, it is not known if she is also with the Middletons while his parents are away.

William and Kate are only expected to be gone for a week, but George will no doubt be at the forefront of their mind, with both parents having spoken of their love for their son in the past.

"He's a little bit of a rascal, I'll put it that way,” Prince William told CNN back in August. “He either reminds me of my brother or me when I was younger, I'm not sure, but he's doing very well at the moment."
